All of our panelists covered themes and issues addressed by the Discovery initiative, including the importance of open licenses, and the need for machine readable data via APIs to facilitate the easy transfer, aggregation and link-up of library, archives and museum content.

Jon gave some background on the ‘Linked Open Data in Libraries, Archives and Museums’ (LOD-LAM) efforts around the world, talking about how the first International LODLAM Summit held in San Francisco last year helped galvanise the LODLAM community. Jon also covered some recent work Historypin are doing to allow users to dig into archival records.

Julie then covered some of the technical aspects of publishing Linked Data through the lens of the OpenArt Discovery project, which recently released the ‘London Art World 1660-1735’ data. She mentioned some of the benefits of the Linked Data approach, and explained how they’ve been linking to VIAF for names and Geonames for location.

I gave a quick overview of the LOCAH and Linking Lives projects, before giving a heads up to the World War One Discovery project. LOCAH has been making archival records from the Archives Hub national service available as Linked Data, and Linking Lives is a continuation project that’s using Linked Data from a variety of sources to create an interface based around the names of people in the Archives Hub. After attempting to crystallise what I see are the key benefits of Linked Data, I finished up by focusing on particular challenges we’ve met on our projects.

Rachel considered how open data might affect policies, procedures and the organisational structure of the library world. She talked about the Digital Public Library of America, a growing initiative started in Oct 2010. The DPLA vision is to have an “open distributed network of comprehensive online resources that draw on the nations living history from libraries, universities, archives and museums to educate, inform, and empower everyone in current and future generations”. After outlining how the DPLA is aiming to achieve this vision, she explained how interested parties can get involved.

There’s an audio recording of the panel on our session page, as well as recordings of all sessions mentioned below on their respective SXSW pages. I’ve also included the slides for our session at the bottom of this post.

Not surprisingly, there were plenty of other great sessions at SXSW. I’ve picked a few highlights that I thought would be of interest to readers of this blog.

Probably of most relevance to Discovery was the lightening fast ‘Open APIs: What’s Hot and What’s Not’ session from John Musser, founder of Programmableweb.com, who gave us what he sees as the eight hottest API trends. He mentioned that the REST style of software architecture is rapidly growing in popularity, being regarded as easier to use than other API technologies such as SOAP (see image below). JSON is very popular with 60% of APIs now supporting it. It was also noted that one in five APIs don’t support XML.

The rise of REST – ‘Hot API Protocols and Styles’ from John Musser of Programmableweb.com at SXSW 2012

Musser suggested that APIs need to be supported, with Hackathons and funded prizes being a good way to get people interested. He noted that the hottest trend right now is that VCs are providing significant funding to incentivise people to use their APIs, Twilio being one of the first to do this. He also mentioned that your API documentation needs to be live if you’re to get interest and maintain use. Invisible mashups are also hot, with operating systems such as Apple’s OS cited as being examples of such. Musser suggests the overall meta-trend is that APIs are now ubiquitous. John’s now made his slides available on slideshare.

The many users of laptops amongst us will have been interested to hear about the ‘Future of Wireless Power’. The session didn’t go into great detail, but the message was very much “it’s not a new technology, and it’ll be here very soon”. Expect wireless power functionality in mobile devices in the next few years, using the Qi standard.

Some very interesting folks from MIT gave the thought provoking ‘MIT Media Lab: Making Connections’ session. Joi Ito, Director of MIT Media Labs explained how it’s all about the importance of connecting people, stating that “we’re now beyond the cognitive limits of individuals, and are in an era where we rely on networks to make progress”. He suggested that traditional roadmaps are outmoded, and that we should throw them away and embrace serendipity if we’re to make real progress in technology. Ito mentioned that MIT has put significant funding into undirected research and an ‘anti-disciplinary’ approach. He said that we now have much agility in hardware as well as software, and that the agile software mentality is being applied to hardware development. He pointed to a number of projects that are embracing these ideas – idcubed, affectiva, sourcemap and formlabs.

Josh Greenberg talked about ‘macroscopy’ in the ‘Data Visualization and the Future of Research’ session, which is essentially about how research is starting to be done at large scale. Josh suggested that ‘big data’ and computation are now very important for doing science, with macroscopy being the implementation of big data to research. He referred to the ‘Fourth Paradigm’ book which presents the idea that research is now about data intensive discovery. Lee Dirks from Microsoft gave us a look at some new open source tools they’ve been developing for data visualisation, including Layerscape, which allows users to explore and discover data, and Chronozoom, which looked useful for navigating through historical big data. Lee mentioned Chronozoom was good for rich data sources such as archive & museum data, demoing it using resources relating to the Industrial Revolution.

So that was about it for the sessions I was able to get to as part of the SXSW Interactive conference. It was a really amazing event, and I’d highly recommend it to anyone as a great way to meet some of the top people in the technology sector, and of course, hear some great sessions.
